  • Patent number: 11123335
    Abstract: The present invention relates to a method for inhibiting lung diseases in smokers and non-smokers by blocking growth factor signaling using an antihypertensive drug, and more particularly, to a pharmaceutical composition for preventing lung cancer or emphysema, which contains an antihypertensive drug as an active ingredient. The present invention suggests a novel use of an antihypertensive drug which is being used in clinics, to prevent lung diseases, and therefore, may be readily applied to early lung cancer or a lung cancer high-risk group, and particularly may exclude safety concerns accompanying clinical application of novel drugs, thereby increasing clinical applicability. In addition, enormous costs and time needed from development to clinical use of new drugs may be dramatically reduced.
